With age, most body organs begin to deteriorate in their function. This happens to the brain also, thereby reducing the overall speed of functioning of most organs. While slowing of bodily movement is visible, the internal organs functioning also slows down, which is not that obvious. Memory loss or dementia is one of the main manifestations of this degeneration of the brain.

Alzheimer s is the most common form of dementia, and the associated symptoms includes reduced reasoning abilities and cognitive defects. Though it is seen only in the elderly, not all elderly people will have Alzheimer s. The overall quality of life of the affected person is reduced with difficulty remembering things that were recently learned. It is a progressive disease and as it gets more severe, a full-time caretaker may be required.

Causes: The brain cells are affected by protein masses known as plaques and tangles. These hamper the way communication between the brain cells happens as well as affect nutrition from reaching all parts of the brain. This leads to shrinking of the brain, eventually leading to memory loss and other problems. There is also a strong genetic linkage, as most people with Alzheimer s have the lipoprotein A gene.

Symptoms: Though memory loss is the most common symptom, there are other symptoms:

Being confused about places, people, and times
Inability to find the right words during conversations
Regular objects are misplaced
Becoming irritable, (in someone who was not so previously)
Mood swings
Personality changes
Inability to organise thoughts
Not able to make the right decisions
Repetitive talks and actions
Forgetfulness (not something the person always does)
Difficulty with numbers (again, not something calculations
Difficulty managing everyday tasks and minor problems
Suspicion of others (like immediate family members and friends)
Risk factors: While age is definitely a risk factor, the fact that not all aged people develop Alzheimer s is to be borne in mind. Other risk factors include the history of stroke, high cholesterol, high blood pressure, diabetes, smoking, obesity, and poor lifestyle choices.

Diagnosis: While there is no definitive way to diagnose Alzheimer s, symptoms along with brain scans and neuropsychological function testing are useful ways to confirm the diagnosis.

Treatment: This is aimed at two things reducing the rate of disease progression and treat (or reverse) symptoms if possible.

Cholinesterase inhibitors improve cellular communication in the brain and also manage depression and agitation. Memantine is used to slow the pace of disease progression.
In people with the disease, small changes are useful to help them with the symptoms. These include keeping essential things like keys and wallet in the same place, keep a daily diary to help them remember things, keep pictures of friends and family within visible distance.

Alzheimer's - An Overview!

What is Parkinson s disease?
Parkinson s disease is a progressive and degenerative disorder of the Central Nervous System that mostly affects older people. It is a chronic disease and the symptoms develop over a period of time. The characteristic symptoms of Parkinson s are rigidity, shaking, bradykinesia (slowness in movement) and shuffled gait. Anxiety and depression also seem to be common in advanced stages of Parkinson s disease. In addition to the motor symptoms, the cognitive function of the brain is also compromised.

Degeneration of the nerve cells in the substantia nigra of the brain results in the reduction in production of dopamine which is a neurotransmitter in the brain. Neurotransmitters relay impulses from one nerve to the other. This is what is mainly responsible for the motor symptoms in Parkinson s. Although, Parkinson s is not a curable disease, it can be controlled and the progress of the disease can be kept in check with certain medications.

What causes Parkinson s disease?
The cause of Parkinson s is mostly idiopathic, i.e. the cause is unknown and is not specific. However, there have been cases which show that it can be attributed to factors such as genetic and environmental factors.
What are the symptoms of Parkinson s?

The symptoms of Parkinson s can be classified as Motor symptoms and Non-motor symptoms:

Motor Symptoms 

Bradykinesia: Slow movement
Tremor of limbs
Rigidity or stiffness of trunk and limbs
Impaired balance and difficulty in coordination or postural instability
Non-motor Symptoms 

Depression
Anxiety and fear
Loss of energy and fatigue
Constipation
Excessive salivation
Weight gain or weight loss
Cognitive problems such as difficulty in remembering, confusion, dementia
Parkinson s disease is not curable, but when detected early, medicines are prescribed to give symptomatic relief. Dopamine substitutes are prescribed to the patient to relieve the motor symptoms.

Parkinson's Disease - Understanding The Motor & Non-motor Symptoms!

Dementia cannot be singularly regarded as a specific disease, but rather indicates a group of symptoms associated with your memory, cognitive thinking, and social abilities, up to the point where daily functioning gets affected. In most cases, dementia steadily worsens over time (progressive dementias). Dementia is not to be confused with memory loss alone; because it is natural with old people to experience memory loss, but that does not necessarily mean they have dementia. If the reason is dementia, then you may require medical treatment.

Causes

Dementias are generally caused either by damage to or changes in the nerve cells operating in the brain. The causes can be grouped differently based on the type of dementia experienced and the part of the brain affected. While some causes can be reversed with effective treatment, others, unfortunately, cannot.

The most common causes of dementia which cannot be reversed include:

1. Alzheimer's disease
2. Vascular dementia
3. Parkinson's disease
4. Frontotemporal dementia
5. Dementia with Lewy (dementia which is neurodegenerative and progressive in nature) bodies
6. Severe head injuries

Other irreversible causes which are relatively rarer than usual include:

1. Huntington's disease (breakage of the brain's nerve cells)
2. Creutzfeldt-jakob disease (irreversible and fatal brain disease)
3. Multiple sclerosis or amyotrophic lateral sclerosis
4. Infections like syphilis
5. Leukoencephalopathies (diseases affecting the brain's'white' areas)
6. Brain injuries
7. Multiple system atrophy

Causes of dementia which can be treated include:

1. Hypothyroidism
2. Heavy metal poisoning
3. Certain brain tumors
4. Chronic alcoholism
5. Hiv/aids
6. Vitamin b12 deficiency
7. Medicinal side effects or abnormal drug reactions
8. Normal pressure hydrocephalus
9. Certain cases of encephalitis

Symptoms

Symptoms of dementia include:

1. Memory loss
2. Difficulty finding the right words
3. Difficulty exercising judgments, especially during emergencies
4. Inability to recall particular events or to recognize people and places
5. Depression or other mood disorders, in addition to symptoms like uncontrolled aggression or constant agitation.

Causes and Symptoms of Dementia

One of the common ailments in the elderly people is the Parkinson s. A progressive disorder, when left untreated, results in worsening of the symptoms. Hence, it is essential to understand the treatment options available to manage the condition effectively. You may be suggested surgical therapies if medication is not effective enough to treat the symptoms.

Surgical treatment options can be beneficial for patients who are suffering from symptoms, but they do not help with treating the disease. In the past, surgical methods like Thalamotomy and Pallidotomy were used to destroy brain cells that contributed to the symptoms. While these methods are still used, they are very rare and situational.

Deep Brain Stimulation (DBS), an FDA-approved procedure, has become much more popular as it is much safer and does not involve invasive surgery. Instead of destroying brain cells like traditional methods, DBS involves sending electric pulses to the affected brain cells to reduce the symptoms. It is not a treatment procedure, but a means of bringing down the severity of Parkinson s to allow better and more comfortable treatment.

Deep Brain Simulation   Who are the right candidates?
Deep Brain Simulation is commonly used for Parkinson  s disease, but it is not recommended for everyone. It is a preferred method of treatment for people who have had Parkinson s for at least four years but have complications which include long periods of time where medications do not work, or symptoms return, uncontrolled and involuntary movements or the freezing/stiffness in the body.

Deep Brain Simulation is not recommended for those who have Dementia as it can lead to memory problems. The general rule of thumb that neurosurgeons follow is that Deep Brain Simulation can help with symptoms that do not get better with medication. DBS can help reduce medication requirements for patients as well as reduce the side effects that may occur due to medication.

Disorder specialists and neurosurgeons can conduct tests to determine if DBS is going to be effective for a patient before going ahead with such a procedure. An extensive assessment is necessary to understand the symptoms, the effect of Parkinson's drugs and also brain imaging is done. All of the expected benefits are then evaluated for the patients, and if the procedure can help alleviate the symptoms, DBS is given a green signal by neurosurgeons and patients can undergo the procedure.

How Does Deep Brain Simulation Work?
Deep Brain Simulation is a very complex procedure. Brain cells communicate with the rest of the body through electric signal, and these become irregular and do not work properly when affected by Parkinson's. DBS smoothens the functioning of these brain cells and reduces symptoms through electric pulses through the implantation of a medical device known as neurostimulator which is also referred as brain pacemaker.

But, as with any treatment procedure, DBS has potential risks and side effects, hence discuss with neurosurgeon thoroughly to access the suitability.

Adopting Deep Brain Stimulation For Parkinson's disease

Aging comes with many health problems including mild hearing loss. Usually, this mild hearing loss does not come alone. According to medical studies, adults, particularly males with hearing loss, mild or severe, are at a higher risk of developing Dementia and Alzheimer s disease. The risk increases as the hearing loss worsen. People with mild hearing loss are at twice the risk of developing dementia compared to people with normal hearing.

Dementia is a group of symptoms and diseases that affects the thinking, memory and social abilities that interfere with the daily functioning of an individual. However, memory loss alone does not mean that one has Dementia. Out of the many causes, Alzheimer s disease is usually the cause of Dementia. Alzheimer s disease is a progressive disease that affects the brain cells to degenerate and dies, destroying memory and other mental functions. 

How Hearing Loss Causes Alzheimer s?

According to medical studies, hearing loss causes several brain changes which increase the risk of developing Dementia. Hearing loss can lead to brain shrinkage, the process in which the section of the brain responsible for hearing becomes inactive. This condition leads to loss of tissues and alterations in the brain structure, developing as the first connection between hearing loss and Alzheimer s. Studies show that the brain of people shrinks more quickly who have hearing loss as compared to the brain of an individual with normal hearing. 

The second link created with an overwhelmed or overloaded brain. In hearing loss, the brain works overtime in understanding what others are saying. When the brain strains too much only for hearing every time and every day, it exhausts an individual s mental energy and snatches the brainpower required for other important mental functions, such as thinking, remembering and acting. This can further lead to Dementia, Alzheimer s and other mental disorders. 

Hearing Aids to prevent Dementia and Alzheimer s

According to various studies, hearing aids are not only helpful in improving one s hearing but they can also preserve an individual s mental and emotional health. Early diagnosis and treatment of a possible hearing loss help reduce risks later in life.

At times, the symptoms of undiagnosed hearing loss are mistaken with the symptoms of Alzheimer s. Hearing impairment makes it challenging for an individual to listen and respond to verbal signs. It increases the feeling of confusion, paranoia, and isolation. 

Hearing aids can relieve the symptoms of Alzheimer s. According to a study hearing aids slow down the rate of memory loss and improve an individual s quality of life.

Takeaway

Adults, especially males with hearing loss have a greater tendency of developing Dementia and Alzheimer s. Hearing loss causes brain to overwork leading to the loss of important mental functions. Hearing impairment can worsen the symptoms of Dementia and Alzheimer s. 

Hearing aids do help in improving the condition and symptoms of Alzheimer s and improve one s quality of life. A timely diagnosis can make a big difference.

Dementia And Alzheimer's Disease In Elderly - Could Hearing Loss A Reason?

Diagnosing dementia can be more difficult than you can imagine. Medically, the patient needs to have at least two areas of mental functionality impaired to an extent where it interferes with their everyday life. However, diagnosis is just the beginning as treating dementia can be even more challenging. Here is a look at some of the treatment options available for dementia patients.

 Treatment for Dementia
There is often no cure for most forms of dementia. Treatment relies on the management of the condition, to ensure that the progression can be impeded. With proper treatment, patients can live a relatively normal life for a number of years.

Cholinesterase inhibitors- These medications are used for the treatment of Alzheimer s disease. They are chemical agents that boost the memory and judgment of the patient. The same is also an effective medication for those suffering from Parkinson s disease and Lewy body dementia.
Therapy- Making small changes to some aspects of life of the patient can often yield good results. For instance, clearing the clutter and noise in the house can be an effective way of helping dementia patients deal with their condition. Similarly, creating a safe environment at home with little chance of severe accidents, will ensure the safety of the patient.
Stress in caregivers of dementia patients
Dementia patients need to be cared for, ideally by a close family member such as a spouse. However, these caregivers undergo a lot of stress while providing support to the patient. For instance, Alzheimer s patients often do not recognize their caregiver who may also be their spouse. Here are some burdens that caregivers have to deal with.

Anger- The sense of fury towards the patient can be strong after years of providing care. They may also be frustrated with the fact that the affected person is unable to perform simple everyday jobs, such as brushing their teeth or tying their shoelaces.
Anxiety- A sense of hopelessness regarding the future is common. It is also the fear of what new challenges the next day might bring.
Depression- Seeing their loved one s mental state deteriorating with each passing day can be difficult to handle and pushes some caregivers into depression.
With such continuous emotional and physical stress, caregivers often fall sick themselves. This is why it is necessary to maintain a bright outlook and remember that a dementia patient can only get well if they have the full support of the caregiver.
